Product Description

Gentle Retinol Serum that Rebuilds Skin Overnight.

  • 2026 Beauty Shortlist Awards: Winner for Best Retinol Serum for All Skin Types.
  • Combines encapsulated retinol with nourishing oils for minimal irritation
  • Enhanced with rosehip and carrot extract for complementary vitamin A benefits
  • Reinforces skin barrier with ceramides and essential fatty acids
  • Calms potential retinol sensitivity with herbal anti-inflammatories

Deep Midnight enhances our original Midnight serum with the addition of pure, vegan, encapsulated retinol. This oil/gel hybrid maintains the nourishing and soothing properties of its predecessor while introducing retinol benefits in a gentle delivery system. The encapsulation technology helps ensure the retinol remains stable and releases gradually into the skin, minimizing potential irritation.

Retinol & Vitamin A Synergy Formula

What distinguishes Deep Midnight from typical retinol products is its comprehensive approach to skin support. The formula contains increased concentrations of Rosa Canina (rosehip) seed oil and carrot extract, delivering complementary forms of vitamin A and beta-carotene that work alongside retinol to enhance results without increasing sensitivity.

Protects Skin's Barrier

The serum's matrix of essential fatty acids provides nourishment, while ceramides reinforce the skin's natural barrier function. Lupine sterols contribute phytosterols that help maintain skin's lipid balance, and herbal infusions of chamomile, yarrow, calendula, and marshmallow help counter potential retinol-induced sensitivity. Antioxidant-rich ingredients like broccoli seed oil, cranberry seed oil, and sea buckthorn extract provide protection against oxidative stress.

Deep Midnight's unique oil/gel consistency allows for effective penetration while maintaining a lightweight feel. The neroli-dominant essential oil blend adds a pleasant sensorial element. The serum is packaged in a black violet glass bottle with a pump dispenser to protect from light degradation and maintain potency.

Using this Serum

Experience it

Deep Midnight transforms from a rich amber-hued gel-oil into a silky emollient that glides across the skin with surprising lightness, absorbing rapidly without leaving a greasy film. The neroli-dominant aroma offers a sophisticated citrus-floral bouquet that creates a calming sensorial experience perfect for evening use. Unlike typical retinol products that can feel drying, this serum delivers immediate comfort and hydration—with skin feeling noticeably smoother and plumper by morning, without the tightness or flakiness often associated with retinol treatments

How to Use it

Incorporate Deep Midnight into your evening routine after cleansing and toning, applying 2-3 pumps to slightly damp skin for optimal absorption before adding any additional moisturizer if needed. Begin with application 1-2 times weekly before gradually increasing frequency based on your age: three times weekly for those in their 30s, four times for 40s, and five times for 50s and beyond. Always wear broad-spectrum SPF during daylight hours and avoid combining with exfoliating products on the same evening. For enhanced results, pair Deep Midnight with a simple, hydration-focused routine on retinol nights.

Why You Need it

Deep Midnight redefines retinol treatment by solving the primary challenges that prevent many from experiencing its benefits—it delivers professional-grade results without the dryness, irritation, or complex multi-product protocols typically required. This all-in-one formula eliminates the need for separate serums, oils, and barrier repair products, saving you time and ensuring active ingredients work in harmony. The intelligent formulation strengthens your skin's resilience over time, providing classic retinol benefits of smoother texture, diminished fine lines, and more even tone, while your skin becomes progressively more healthy and balanced—making Deep Midnight not just an anti-aging treatment but a comprehensive skin health investment.

Key Ingredients in Deep Midnight Retinol Serum for Overnight Repair

Encapsulated Vegan Retinol

Retinol delivered in a slow-release capsule, which means your skin gets a steady, tolerable dose instead of one big hit that causes flaking and redness. All the cell-turnover and collagen-stimulating benefits of retinol with significantly less irritation.

Ceramide Complex

Ceramides are the essential lipids naturally found in your skin that help maintain its protective barrier and retain moisture. Our ceramide complex mimics your skin's natural structure to replenish and restore what time and environmental factors deplete. This powerhouse ingredient strengthens your skin's defense system, preventing moisture loss while protecting against irritants and pollution. By reinforcing the skin's natural barrier, ceramides help reduce sensitivity, dryness, and visible signs of aging—leaving skin looking healthier, plumper, and more resilient.

Lupin (Lupinus Albus) Seed Extract

A peptide-rich botanical extract that supports skin firmness by stimulating collagen and elastin synthesis. Clinical studies show visible improvement in skin density and elasticity. A plant-based alternative to synthetic peptides that actually delivers.

Frequently Asked Questions

Can retinol burn or irritate your skin?

Conventional retinol can cause burning, peeling, and redness — particularly in the first few weeks of use — because it delivers a high concentration all at once. Deep Midnight uses encapsulated retinol, which releases gradually into skin rather than all at once, significantly reducing irritation potential. The formula also contains chamomile, yarrow, calendula, and marshmallow herbal infusions specifically to counter retinol-induced sensitivity, making it suitable for all skin types including those who've struggled with retinol before.

What is encapsulated retinol and why does it matter?

Encapsulated retinol is retinol enclosed in a protective shell that breaks down gradually on skin, releasing the active ingredient slowly and steadily rather than all at once. This slow-release mechanism delivers the same collagen-stimulating, cell-turnover benefits as conventional retinol with significantly less irritation, dryness, and peeling. It also improves stability — retinol degrades quickly when exposed to light and air, and encapsulation protects it. Deep Midnight packages it further in violet glass to preserve potency.

Can you use retinol with vitamin C?

Traditionally, retinol and vitamin C were considered incompatible because L-ascorbic acid requires a low pH that can degrade retinol. However, Deep Midnight uses encapsulated retinol and City uses tetrahexadecyl ascorbate — an oil-soluble, pH-independent form of vitamin C — which means the two can be used in the same routine without conflict. The simplest approach is to use City in the morning and Deep Midnight in the evening, giving each active its own window to work.

What does retinol actually do for skin?

Retinol is a form of vitamin A that accelerates skin cell turnover, stimulates collagen production, and improves the skin's ability to repair itself. Over time this translates to smoother texture, reduced fine lines, more even skin tone, and clearer pores. Deep Midnight enhances these effects by pairing retinol with rosehip oil and carrot extract — complementary sources of vitamin A and beta-carotene — alongside ceramides that reinforce the barrier as retinol does its work.

How often should you use retinol?

Start slowly — once or twice a week — and build up as your skin adapts. Deep Midnight offers a useful age-based guideline: three times weekly for those in their 30s, four times for 40s, and five times for 50s and beyond. Always apply at night, as retinol increases sun sensitivity. On retinol nights, keep the rest of your routine simple — avoid exfoliants or other actives, and follow with SPF the next morning without fail.

Is retinol safe to use during pregnancy?

The current medical consensus is that retinol and all vitamin A derivatives should be avoided during pregnancy. While topical retinol absorbs at much lower levels than oral vitamin A supplements, most dermatologists and OBGYNs recommend erring on the side of caution given the known risks of vitamin A overexposure during fetal development. We'd always recommend consulting your doctor or midwife before using any retinol product while pregnant or trying to conceive — this is genuinely one where a medical professional's guidance matters more than a product page. If you're looking for pregnancy-safe alternatives that still support skin health overnight, Midnight (our retinol-free oil serum) covers similar barrier-repair territory without any vitamin A actives.
